The graph looks more like burning tests than continuous mining...

I connected EPS_12v_2 with the new PSU. Apparently this isn't required but it might help if going to 4 modules.

Problem solved.

I replaced again the PSU this time with a OCZ ZX 850W (as a reminder: original Enermax GX750 was DOA, my first replacement Corsair GS800 2013 Edition couldn't handle the load with 3 modules)

The Avalon just did a 65GH/s mining sprint of 14h without any reboot or weird error messages in System log.

For the USB errors, thanks to the people that suggested solutions (fpgaminer, xiangfu, ...), if it get real bad I have a raspi lying around that I will use to replace the TP-Link.

I have reviewed all this thread and beside the dead PSU which is not related, the stability issues are 100% the same.. same kernel messages, same cgminer messages

I have upgraded to beta firmware 20130519 because it can't be much worse...

After around 45minutes, mining stopped:

I'm feeling special.

I'm using wired.

I disconnected 1 module and it mined for 5 minutes then the hashrate went to 0, but the box didn't reboot.

I disconnected 2 modules (so 1 module left) and now it has been stable and mining at ~22GH/s for 25 minutes. That's still 10 times better than my previous GPU rig.

It seems the EPS_12v_2 connector is required to run with more than 1 module.

So my quest is now a "in stock" PSU at a local dealer with 2 PCI-E and 2 EPS (CPU) plugs. So far I found an OCZ ZX 850W in stock.

Hi,

I got my Avalon Batch #2 delivered. (France)

Unfortunately, the PSU was completely dead on arrival (Enermax GX750)

I picked up a Corsair GS800 (which is listed as approved PSU on the wiki) at the local shop. Unfortunately (again, im being lucky) Corsair released a "2013 Edition" with has fewer options than the original GS800: 2 connectors are missing.

So I recabled my Avalon but I don't have a connector for the "EPS_12V_2" since this PSU has only one "CPU cable".. so i left EPS_12V_2 empty...

Cabled:
ATX
PCIE_12V_1
PCIE_12V_2
EPS_12V_1

Not cabled:
EPS_12V_2

The Avalon started on the new PSU (which was a HUGE relief) and managed to mine during around 10 minutes... then it rebooted. I don't know if it's related to the missing EPS_12V_2 plug.

Is this bad ? Is there a risk of overloading the other rails ?

Firmware: 20130419

Any advices welcome.

Can a kind soul take measurements of the unit ? (height, width, depth) It's not yet on the Wiki.

Thanks

Some serious airflow problem there.

Can you remove the useless 2"1/2 harddisk bay ? It's the airflow from the front fan. Move your harddisk higher above in the 5"1/4 bay.

Also try to clean the cable mess in front of the card.

As for the top card being the hottest, that is expected, heat rises and you have no space between your cards, each card is cooking the card above.

According to the AMD specs, it's a single GPU card with 800 SP.

It's video card equivalent is a Radeon HD 4870.

That should give you around ~200Mh/s

FireStream 9350 and 9370 just starts to be interesting, these being equivalent to Radeon HD 5850 and 5870.

On a rajouté la possibilité de payer en Bitcoin ainsi que les prix en Bitcoin sur notre site de vente de Webhosting/VPS/SSL/Nom de domaine le week-end passé:
